Hardware Set-up

Important: Switch off all equipment before starting the set up.

Connecting the CORIOscan Pro to a computer and monitorDis-connect the monitor from the computer at the computer's video output. Connect thiscable to the 'VGA OUT' socket on the back of the CORIOscan Pro. Apple Macintoshand workstations will require an additional cable. This will let you see the monitor asbefore, even when there is no power to the CORIOscan Pro.

Use the supplied computer-to-unit (15 pin to 15 pin) cable to connect the CORIOscanPro to the computer monitor output. Apple Macintosh and workstations will require anadditional cable. Connect this to the 'VGA IN' socket on the back of the CORIOscan Proand to the monitor output on the computer.

Rear of CORIOscan Pro desktop version. Rack-mount versions are identical - with thedouble rack-mount having two identical sets of outputs.

Connecting the video outputsThe CORIOscan Pro provides several different output types to allow connection tovarious video displays and capture equipment (such as TVs and VCRs). The choice ofoutput type depends on what your equipment can accept.

Composite Video - use the composite video lead provided to connect from thecomposite video output on the back of the CORIOscan Pro (the BNC socketmarked CV) to the composite video input of your target video equipment.

S-Video - use the S-Video lead provided to connect from the S-Video output onthe back of the CORIOscan Pro to the S-Video input of your target videoequipment. S-Video provides improved performance over Composite Video.

RGB & Sync. Use a 4xBNC to 4xBNC cable to link from the red, green, blue,and HS/CS outputs to the video display. The CORIOscan Pro defaults tooutputting negative-going CS (Composite Sync) on the HS/CS connector, but ifyou encounter problems then it is likely that this has been changed - see'Advanced Features' later in this manual.

RGB & H/V Sync. Use a 5xBNC to 5xBNC cable to link from the red, green,blue, HS/CS and VS outputs to the video display. The CORIOscan Pro defaults to

3

outputting CS (Composite Sync) on the HS/CS connector and VS, so you must see'Advanced Features' later in this manual in order to change this to the requiredseparate HS & VS. It is recommended that another output is used, until operationof the unit is understood.

RGB / SCART connection. Most European TVs and Video recorders use thisconnection, and the cable for this is optional. Connect the SCART cable to yourTV or video, and the BNC plugs into the correct connectors on the back ofCORIOscan Pro - normally the cable coloured white, grey or yellow goes to CV(composite video), and black goes to HS/CS (used for the SCART 'blanking'signal). The CORIOscan Pro defaults to outputting CS (Composite Sync) on theHS/CS connector, but if you have problems then it is likely that this has beenchanged - see 'Advanced Features' later in this manual. If you have problems, it isrecommended that another output is used, until operation of the unit isunderstood.

YUV connection. Professional equipment may require YUV signals, and theseare connected from the same outputs as the RGB signals, also labelled 'R-Y', 'Y','B-Y'. If the CORIOscan Pro is set to output RGB mode (this is the default) it willbe necessary to switch to YUV - see the section on switching between RGB andYUV modes in the Advanced Features section of this manual. It is recommendedthat another output is used, until operation of the unit is understood.

Connecting the serial cable (optional)The CORIOscan Pro can be controlled from a computer, and used as a remote mouseemulator by connecting its RS232 port to a computer's RS232 port. See the section on'RS232 Computer Control' later in this manual on how to use this control feature (mouseemulation is the default, and merely requires connecting a suitable RS232 lead).

Connecting a mains adaptorThe CORIOscan Pro requires a 12v DC minimum 500mA power supply - see 'TechnicalSpecifications' for further information on suitable power supplies. With the on/off switchon the front of the CORIOscan Pro in the off (up) position, plug the round 'DC powerplug' of the mains adaptor into the 'DC in' socket on the back of the CORIOscan Pro.Plug the mains adaptor into a mains outlet and switch on at the mains outlet beforeswitching the on/off switch on the front of the CORIOscan Pro to the 'on' (down)position.

Turning onMake sure that all leads are connected and that all other equipment is turned on - yourcomputer monitor should be functioning normally. The CORIOscan Pro should beswitched on at the mains socket before switching on from the on/off switch on the front

4

panel. Select the correct line input (AUX or AV) on the target video equipment. TheTV should now be displaying the same picture as is on the computer monitor.

When the CORIOscan is switched on the green LED indicator on the front panelwill illuminate and the LCD will display the version and copyright details beforecycling through the current status settings of the unit. If this does not happenplease refer to the trouble shooting section.

If there is a picture on the video monitor, but it is the wrong shape, position orcolour it may be necessary to alter some of the status settings before a good pictureis displayed. For example: it may be necessary to switch to PAL or NTSC settings.Further details on selecting the correct settings for your displays follow in theAdvanced Features section.

If there is no picture on the video monitor then go to the trouble shooting section -one possible cause is that the YUV output is enabled, as this will blank all otheroutputs. This is also covered in the Advanced Features section.

About the CORIOscan ProThere are 3 ways to control the CORIOscan Pro:

1. By the buttons on the front panel

2. By the infra-red remote control unit

3. Directly from the computer via the serial (RS232) port

However, all control is based on the operation of the front panel, so to correctlyunderstand the way in which to use the unit this manual will first describe this method ofcontrol. Descriptions of the infra-red control method, and serial control from thecomputer are described later.

Shown below is a diagram that indicates the main features of the front panel. Whilst therack-mount version may look slightly different, the operation is identical to the desktopversion.

Figure 7.

LCD - the top line of the liquid crystal display (LCD) always indicates the currentmode of the CORIOscan Pro unit. At power-up, this will be STATUS mode, butthis will change depending on what the user wants the unit to do. The bottomline always indicates the value that is or will be adjusted by the various controlmethods.

MENU. This is used to initiate front panel control of the unit, and select thevarious options and features to change.

OVERSCAN/-. This is a dual purpose button that will be described in a moment,but is normally used to decrease (or unset) an option or feature.

FREEZE/+. This is another dual purpose button, but normally used to increase(or set) an option or feature.

On/off Switch - this switches the CORIOscan Pro on and off. Note that this willnot prevent the mains adaptor from being active.

LED - this is illuminated when the CORIOscan Pro is on.

Sounder. The internal sounder is used to confirm that a setting has changed, andto indicate that the CORIOscan Pro is saving settings to non-volatile memory.You will hear it a fair bit during normal use, but it can be disabled if needed.

Quick-Set buttonsThese are the dual purpose buttons described earlier, and only function when in Statusmode (i.e. the top line of the LCD says 'Status').

They are provided for quick access to certain often-used functions - i.e. TogglingUnderscan and Overscan, and Freeze.

Special multi-hold buttonsCertain buttons can be held together to perform other functions. These include:

Engineering Reset. Hold down MENU and - together for about 2 seconds. Thiswill reset the unit to Factory settings. It should only be used if the unit's settingsgive an invalid output that the user cannot exit from, as all user-settings will belost.

Store Settings. This is done by holding the MENU and + buttons in together forabout 2 seconds, and can be done at any time. This stores the current settings(e.g. Overscan, YUV mode, etc.) in Non-Volatile Memory, which will be readback the next time the unit is turned on.

Both options will emit a high-pitched beep when complete to indicate that data has beensuccessfully stored - or in the case of the Engineering Reset, overwritten with the factorydefault data.

(If you hear high pitch beeps at other times, it indicates that other data is being storedinto memory - eg. information the CORIOscan Pro has deduced about the graphicsresolution coming from your computer.)

Menu structure and feature controlThis section goes through the main menus available via the LCD, and what control theyhave over the unit. Internally, the Infra-Red and Serial control links change the featuresin the same way as the buttons, so this section is required reading whatever the finalmethod of control is likely to be.

Advanced features are covered in the next chapter.

Quick-Set controls - when in Status modeOverscanThis is controlled by the 'OVERSCAN' quick-set button when in 'Status' mode. It togglesbetween underscan and overscan displays on the TV set:

Underscan is where a border is left around the edge of the computer image whendisplayed on the TV.

Overscan is where the image is intentionally too large to fit on the TV, thusensuring that no border or edge can be seen.

Both sizes are user-adjustable, and the method of doing so will be described later underthe 'Screen Size...' section.

FreezeThis is another quick-set button, labelled 'FREEZE'. When pressed the first time, theunit will enter a special mode where the video image and all other features are frozen.

Freeze will remain active until disabled by pressing 'FREEZE' again, and thewhole unit will remain frozen until this happens.

No other features are accessible whilst in Freeze mode.

MENU Adjust ModeYou can enter this by pressing the MENU button once. This enters the beginning of anumber of sub menus that allow complete control over the unit features.

The various options from this menu, all selected by pressing MENU repeatedly, are:

Flicker ReductionThe unit defaults to using a 4-line filter, which is best for 800x600 displays. Pressing +or - when this option is displayed will change this to 2-line or 6-line.

2-line mode is not advisable, unless the vertical image softening that is presentbecause of higher flicker reduction modes needs to be avoided. Line droppingwill be common in this setting.

4-line mode is best for resolutions around 800x600, but is down to personal taste,and the exact nature of the graphics or text being displayed. Thin horizontal lines

8

cause the most flicker, and if this is seen, then the highest flicker reductionfiltering should be done.

6-line offers the maximum amount of flicker reduction, and allows images (evenCAD wire-frame drawings) to be displayed up to a resolution of 1600x1200without line dropping. This mode may not be suitable for low resolutions,because of excessive softening of the image - but again this is down to personalpreference.

Auto SetThis is a powerful feature of the CORIOscan Pro unit, and will make the unitautomatically scan the computer image to determine its size and position within the RGBsignal that it is receiving. This then lets the unit scale and position this on the TV setautomatically, without further user intervention.

Pressing the + button will start this scanning, and it will take about 15 seconds. Duringthis time the image on the TV will move around, but at the end of this the image shouldbe stable and correctly centred. Note that:

Until you run this feature (assuming you have not previously done so), the unitwill have 'guessed' the right settings in order to give a video output that is centredand sized correctly. This 'first guess' is exactly that: a guess - as graphics cards incomputers have very few 'standard' resolution/refresh rate settings, and all othersettings vary drastically from computer to computer.

This feature requires that the top, bottom, left and right edges are of a certainminimum brightness - i.e. certainly not black, but the actual level can be adjustedand the method to do so is described later. Almost all Windows programs willuse the full size of the display which is fine, but some DOS programs (especiallyat the DOS prompt) may not do so which will cause a problem for the unit.

Only use this feature when the full area of the computer screen is being used - thiswill ensure that the unit 'sees' the edges correctly, and performs its task withouterrors.

If you have a problem, a 'Manual Set' mode is available to fine tune the valuescreated by this mode. Or simply re-activate this feature when your computerscreen is being more fully used.

Once complete, the Auto Set routine will remember this particular computerresolution so that you should not need to re-do the routine. The only exception isif you change the refresh rate, or do an Engineering Reset.

Screen Size...This is a sub-menu, selected by pressing + when the above message is displayed on thelower line of the LCD. It displays a number of values that can be used to adjust theCORIOscan Pro's output to suit your video display device. Note that you should have

9

ideally already done an Auto Set, so that the unit knows what area of the computer imageactually contains the display you want converted to video - otherwise you may have torepeat the adjustments for different screen resolutions.

The values shown depend on whether you are in Underscan or Overscan mode, somake sure you have the appropriate one selected before proceeding to change thevalues.

The values are also separately stored for NTSC and PAL outputs - adjusting onewill not affect the other.

When you finish adjusting the values, press + when you reach the 'Exit' message.This will return you to the 'Screen Size...' menu option, and you can continue tofurther sub-menus by pressing MENU as before.

If you like the new settings, use the multi-button features described earlier to rememberthe settings in Non-Volatile Memory. Pressing and holding the appropriate buttonallows fast increasing and decreasing.

Out H-Centre - altering the display's left/right positionThis adjusts the horizontal position of the computer image on the screen. Do not attemptto move the image too far to the left or right, as this may cause image deterioration.Increasing the value (+ button) moves the display to the right, decreasing it (- button)moves it to the left.

Out H-Width - altering the display's widthLike the above option, care should be taken with this option. Press the '+' button toincrease the width of the picture and '-' to decrease it.

Out V-Centre - altering the display's vertical screen positionPress the '-' button to move the picture up and '+' to move it down

Out V-Height - altering the display's heightPress the '+' button to increase the picture height and '-' to decrease it.

You can return to the previous menu by pressing '+' when the 'Exit' message appears.

Zoom...Zoom allows you to view a section of the video picture at twice the normal size. Panningin the zoom mode allows you to select exactly what part of the screen is displayed. Notethat:

Again, it is highly recommended that the user should have already run the AutoSet routine, so that the unit knows exactly where the start and end of the computerimage is within the RGB signal. Otherwise, the user may be able to pan to areasof the computer image that are completely empty.

The Panning settings are remembered when Zoom is subsequently turned off.This could be useful in training applications.

10

It is possible to make the unit start up (from power on) in Zoom mode, and in aparticular pan position. This may be useful for certain applications.

Enter the Zoom... sub-menu by pressing + when this message appears.

Zoom - turning on and offPress the '+' button when 'Zoom Off' is displayed to turn the zoom on and the '-' buttonto turn the zoom off again. Pressing MENU will move to the options to alter the Panningposition.

Pan X Pos - adjusting the horizontal panning positionPress the '-' button once to pan left one step (i.e. move the zoomed image to the left).Similarly, press the '+' button once to pan right one step.

Pan Y Pos - adjusting the vertical panning positionPress the '+' button once to pan down one step. Press the '-' button once to pan up onestep.

Press + when the 'Exit' message is displayed to exit this sub-menu. However, zoom willstill be active until disabled.

Info...This sub menu allows access to information relevant to the current screen resolution, andis used by the CORIOscan Pro unit to determine correct 'input window' settings whenconverting from computer RGB signals to a video output. The 'input window' is the areaof the computer image that is actually used, and is determined by:

Total Lines - for information onlyThis number that appears here shows the total number of horizontal lines output by thecomputer's graphics card that makes up a complete picture. Note that this is always morethan the number of lines usually described when setting up a particular resolution - assome of these extra lines will be used for blanking.

This value cannot be altered, and is for information only.

Refresh Rate - for information onlyThis number indicates the number of pictures displayed by the computer each second.The values typically range from 60 to 85Hz, but can go higher. (Multiplying the VerticalRefresh Rate by the number of lines will give you the Horizontal Refresh Rate.)

Again, this is for information only, but is useful in determining the actual output fromthe computer. Whilst high refresh rates are generally more acceptable when displayed oncomputer monitors, the CORIOscan Pro prefers a low refresh rate so that it's capturecircuitry has more time to capture more pixels, thus giving a clearer picture.

Press + when Exit appears to exit this mode.

11

Manual Set...This sub menu should only be needed when the Auto Set has failed for some reason. Seethe notes on Auto Set before adjusting these parameters, in case something else will solvethe problem.

Otherwise, you can 'teach' the unit the correct horizontal and vertical position and size ofthe computer's RGB output - and thus the CORIOscan Pro will be able to capture this'input window' and display it correctly on the video output.

Whatever adjustments you make, the unit will continually try to fit the 'input window' toyour preferred video output size and position setting. It is highly recommended that thismode is only used when in Underscan mode, or you will not know if you've adjusted thevalues correctly.

Once adjusted, the 'VGA Store' option can be invoked to remember the new settings inNon-Volatile Memory (thus overwriting any previous setting for this screen resolutionand refresh rate combination).

VGA Left - start of image captureIncreasing this value will move the left edge of the 'input window' further to the right -i.e. less of the computer image will be captured into internal memory. Increase this valueuntil the computer image just starts to be cut off, and then decrease by one.

VGA Width - width of captureIncreasing this value will make the input window wider, thus capturing more pixels intothe internal memory. Ideally, only capture just enough pixels to display the wholeimage.

VGA Top/4 - start line of captureSimilar to VGA Left, increasing this value will move the top of the 'input window' down,and start to cut off the computer's image. Decrease by one when this happens. The /4appears because the value shown is the actual line number at which capture starts intothe internal memory divided by 4.

VGA Bot/4 - end line of captureLike VGA Top/4, this determines the last line captured. Decrease until the image juststarts to be cut off, and then increase by one.

VGA Store - store new VGA settingsPress + once to store your new settings. They will now be remembered even when thepower is switched off.

12

Advanced Menus & FeaturesThese features control the basic operation of the unit in order to comply with theoperating environment - e.g. selecting PAL or NTSC video standards, adjusting LCDcontrast, etc.

They are accessed in the same way as the previous features - i.e. from the STATUSmode press the MENU button repeatedly until the LCD displays the message 'Advanced'.Then press the '+' button to select the Advanced sub menu.

Subsequent pressing of the MENU button will select the next Advanced feature to alter.

Any of these new settings can be stored using the 'Store Settings' multi-buttons (holdMENU and + together for approx. 2 seconds).

Advanced...LCD ContrastSet the LCD contrast for optimum visibility with the unit in its desired position, as theangle at which the LCD is viewed at also makes a difference.

To make the LCD text on the display lighter press the '+' button. To make itdarker press the '-' button.

Once set, do a Store Settings so you do not have to do it again - unless you movethe unit's relative position.

Video Standard - PAL/NTSCThe CORIOscan Pro can switch between PAL and NTSC standards with ease.

Press the '-' button to switch to NTSC mode. Press the '+' button to switch to PAL.

Screen Size settings are remembered separately for PAL and NTSC, so changingthe Screen Size settings in NTSC will not affect the PAL settings.

Output Signal - RGB/YUVThe CORIOscan Pro is capable of producing either RGB or YUV outputs. The samethree BNC connectors on the back of the unit supply both RGB and YUV, and in order tooutput the correct format the CORIOscan Pro must be switched to that setting. By defaultit is in RGB output mode. The CORIOscan Pro also has separate BNC connectors toprovide horizontal (HS) and vertical (VS) sync. signals, should your target videoequipment require this - see later in this section.

Note that in YUV mode, the Composite Video and S.Video outputs are disabled!

Having the wrong setting will give incorrect colours on the output from theseconnectors.

Press the '-' button to switch to YUV mode. Press the '+' button to switch to RGB.

13

H. Soften - Image smoothingHorizontal filtering (softening) enables the user to smooth pixels, text and lines in thehorizontal direction, where flicker filtering only allows control over the vertical lineflickering.

This is used to improve the recordability of a video signal - i.e. to reduce itsbandwidth.

H.Soften is not active during Zoom mode - it is temporarily disabled.

Press the '+' button to switch the horizontal soften on, the '-' button to switch itoff.

Sense - for AutoSet functionThe sense level relates to how the Auto Set routine views the video input from thecomputer. If running Auto Set produces a resultant image that is too big for the TV itmay be because the image is too dark for the CORIOscan Pro to correctly find the edgesof the picture. Altering the sense setting will change the brightness needed to find theedges satisfactorily.

A setting of 1 will sense 25% brightness levels, 2 will sense 50%, and 3 will sense75%. 2 is the default, and should be fine for almost all screen displays.

Run the AUTO SET after changing the sense setting to ensure a good image onthe TV. If the image is still not good enough it may be necessary to set theCORIOscan Pro manually - see Manual Set.

To increase the sense value press the '+' button. To decrease it the press '-' button.

IR (Infra Red) - on/offAs there are many different methods of controlling the CORIOscan Pro, multiple usescould be confusing.

This feature is useful when controlling the double 19" rack mount version, so thatonly one unit will respond to the infra red remote control.

It can also be used in situations where stray or random IR signals may be pickedup - or even to prevent others from remotely altering the unit's features.

In order to switch off control from the infra-red remote control press the '-' button,or press the '+' button to accept it.

RGB Term. - Input impedanceThis relates to whether or not the CORIOscan Pro is terminating the computer monitoroutput from the computer with a 75 Ohm impedance.

Usually the CORIOscan Pro will set the termination automatically ('Auto' mode),by sensing whether a computer monitor is linked into the circuit as well (i.e. tothe 'VGA OUT' connector).

However, if necessary, it is possible to turn the termination off - for example if theCORIOscan Pro does not sense that the monitor is attached, which would result in'double-termination' of the RGB signals.

Press the '-' button to turn the termination off, the '+' button to switch to automaticmode.

RS232 - Control/MouseThis switches the use of the RS232 serial port between computer control and mouseemulation

In order to use the RC02 remote control to emulate a mouse, this RS232adjustment must be set to 'Mouse' mode. Similarly, to use a serial link from thecomputer to control the CORIOscan Pro, it must be set to RS232 Control mode.

Note that the default is 'Mouse' mode - you must enable 'Control' mode in order tocontrol the CORIOscan Pro from a computer via the RS232 link.

Press the '-' button to switch to Mouse mode, and the '+' button to switch to RS232Control mode.

Baud rateIn order to control the CORIOscan Pro from the computer it is necessary to set the samebaud rate for both the unit and the controlling computer.

Press the '+' and '-' buttons to change to the required number. The CORIOscanPro does not display the actual baud rate, but a number relating to it. The table ina later section on 'RS232 Computer Control' shows which Baud rate each numberrelates to. For example: to set to 9600 Baud the number must be 23.

"9600,N,8,1" is the default setting - i.e. no parity is used, 8 data bits are required,and 1 stop bit.

This number is only used in RS232 'Control' mode. 'Mouse' mode ignores thisnumber, and always uses 1200 baud.

RS232 IDThis ID code can be used where multiple CORIOscan Pro's are all linked via a serialcable to the same computer. The ID can be altered so that each unit's ID is unique, andthus each unit could be adjustable by itself - with one serial port. This feature isdescribed further in a later section.

Sound - on/offThe internal sounder is used to give an indication of whether a variable has beenchanged, or if the CORIOscan Pro is saving settings to non-volatile memory. If you donot wish any audible indications to be present, the sounder can be switched off.

Normal beeps indicate that a feature or value has been changed.

15

High-tone beeps indicate that something has been written to the unit'sNon-Volatile Memory - for example when doing a Store Settings, EngineeringReset, AutoSet, or when a new screen resolution/refresh rate combination hasbeen detected.

Press the '-' button to turn the sound off, the '+' button to turn it on again.

Comp Sync In - from computerThe CORIOscan Pro does not need to have separate Horizontal and Vertical sync inputsprovided by the computer, it can also accept composite sync signals, or sync-on-green(see next option). This ensures compatibility with as many different types of computer aspossible.

If your computer outputs a composite sync signal it is necessary to switch theCORIOscan Pro to accept it, as the default is to accept separate sync only.

A composite sync signal should be fed into the unit on pin 15 of the VGA INconnector.

Press the '+' button to turn on composite sync input, and the '-' button to turn it offagain - thus requiring separate sync.

Sync/Grn In - sync on greenIf your computer outputs the composite sync signals on the green video signal it isnecessary to switch the CORIOscan Pro to accept it.

Note that Comp Sync In (see previous option) should be turned ON in order forthis to have an effect.

Press the '+' button to turn sync-on-green feature on, and the '-' button to turn itoff again.

Input sync. type Comp Sync In Sync/Grn In

Separate H & V (default) OFF -

Composite sync. ON OFF

Sync. on green ON ON

Sep Sync Out - BNC outputsThe CORIOscan Pro can output either separate horizontal (HS) and vertical (VS) sync.signals, or two composite sync. (CS) signals. These syncs are available from the BNCoutput sockets on the back of the CORIOscan Pro. It is necessary to switch theCORIOscan Pro to give the correct sync. outputs for your display.

By default, the HS/CS connection and VS connection both output CompositeSync.

Turning this feature ON will output HS and VS separately.

16

Note that when using the RGB to SCART cable (optional) this feature must beturned off.

Press the '+' button to turn separate H & V sync outputs on, the '-' button tochange to composite sync output.

Neg Sync Out - BNC outputsThe CS/HS/VS outputs can be either positive or negative signals. It is necessary to switchthe CORIOscan Pro to give the correct polarity sync. to correspond to your target videoequipment.

The default is to output negative going sync. signals.

Press the '-' button to switch to positive syncs, and the '+' button to switch tonegative syncs.

Engineering...Items in this section will alter the basic operation of the CORIOscan Pro. The changesare generally of a highly technical nature and should only be made when they areunderstood. Please read each item in this section carefully before making any alterations.

When the Engineering... message appears, press and hold both the '+' and '-' buttonsimultaneously for approx. 2 seconds, and then release both buttons.

Settings changed in this mode can be stored in NVR the same way as other settings.

ADC Ref. - input RGB levelThe CORIOscan Pro takes the analogue signal destined for the computer monitor andconverts it to a digital signal in order to perform some signal processing and scanconversion. The actual device that does this is an analogue to digital converter (ADC),changing the reference level to this is similar to a brightness control, but will also clipcolours that are too bright to the maximum brightness level. If this is incorrectly set thencertain colours, such as yellow, may appear washed out, or even come out as white. Thisadjustment is factory set and should not normally need altering.

It is highly recommended that this value is only adjusted when problems arise,and even then only when a full colour bar is displayed on the computer screen andan oscilloscope is connected to a video output - thus allowing monitoring of theeffects.

17

Pressing the '+' button increases the voltage at the ADC reference input (thusmaking the sampled image darker, and reducing 'clip' effects), the '-' buttondecreases it (making the image brighter, but at some point will start to 'clip' theRGB input).

DAC Ref. - output video levelThe digital to analogue converter (DAC) changes the digital data output from theprocessing circuit into an analogue form that can be displayed on a standard videomonitor or TV. Altering the reference level has an effect similar to changing the contrastof the output signal.

It is highly recommended that this value is only adjusted when problems arise,and even then only when a full colour bar is displayed on the computer screen andan oscilloscope is connected to a video output - thus allowing monitoring of theeffects.

Pressing the '+' button increases the voltage at the DAC reference input, the '-'button decreases it.

CV Filter - for Composite VideoThe CORIOscan Pro allows some control over the amount of filtering on the CompositeVideo output. Altering this may give a clearer image, or reduce dot-crawl.

In most circumstances, this should never need changing.

Pressing the '+' button increases the value thus applying more filtering, whilst the'-' button decreases it.

SC/H PhaseThis adjusts the phase delay between subcarrier and horizontal sync signal.

This adjustment will usually only be required for studio setups, where the actualphase relationship can be measured.

The value of 4 is the default, and corresponds to approximately 0 degrees shift.The remaining values are indicated below:-

Value 0 1 2 3 4 5 6 7

Phase -180 -135 -90 -45 0 45 90 135

This should enable SC/H phase adjustment to the nearest 22.5 degrees.

Pressing the '+' button increases the phase value, the '-' button decreases it.

Max Pix Freq. - for image captureThe maximum pixel frequency refers to the maximum frequency used to capture pixelsfrom the computer signal. It is a relative value only, and should only be adjusted whentold to do so by an engineer at Vine Micros.

Pressing the '+' button increases the maximum pixel frequency, the '-' buttondecreases it.

18

Clock Width - for A/D convertorThis value changes an internal hardware setting, and should not normally be altered -like Max Pix Freq above, it should only be adjusted when told to do so by an engineer atVine Micros.

The default value is 1. Setting other values may result in incorrect colours orimage streaking.

Pressing the '+' button increases the maximum pixel frequency, the '-' buttondecreases it.

Y/C delay - for video outputThe Y/C delay setting allows control of the delay between the luminance (Y) andchrominance (C) parts of the video signal.

This affects ALL video outputs - composite video, S-video, RGB and YUV.

Pressing the '+' button increases the delay (thus making any colour smearingmove left), the '-' button reduces it (making any colour smearing move right).

Infra Red Remote Control

RC02 Remote ControlThe remote control can be used to control the features of the CORIOscan Pro, change itssettings and control the computer's mouse.

Figure 8.

Make sure you have read the previous sections on controlling the features of theCORIOscan Pro before using the infra-red controller.

The CORIOscan Pro's LCD display will change to show the features altered by theremote control, and a beep will be emitted from the sounder (if it has not been disabled).

Freeze, Underscan, Overscan, ZoomThese all behave identically to the Menu operated system described earlier. Rememberthat when you do an image Freeze, all other functions are disabled until the Freeze isturned off again (either from the R/C, buttons, or RS232).

When Zoom is selected, follow it by pressing Pan in order to start Panning around thescreen.

ResetThis option resets the unit back to power-on defaults. (It is not the same as anEngineering Reset).

SizePressing this once will allow the user to alter first the position of the computer image onthe video output, and then the image size on the video output.

Make sure you have done an Auto Set for the resolution you are using before alteringthese values - or you may have to repeatedly adjust them for each screen mode change.

FilterPressing this button lets the user select Horizontal Softening and (vertical) FlickerReduction using the cursor keys.

PanWhen in Zoom mode, press this button to alter the current pan position using the cursorkeys.

Mouse ControlThe RC02 infra-red controller can emulate a Microsoft Mouse when the CORIOscanPro's RS232 cable is connected to your PC's mouse port.

Make sure that RS232 mode is set to 'Mouse' (see Advanced... menu section formore details), or the CORIOscan Pro will not know that you want Mouse modeenabled.

Once set up, the L.Click, R.Click, and D.Click buttons emulate their appropriatemouse equivalents, whilst the Mouse Cursor buttons allow the mouse pointer to bemoved around.

At the first press of the mouse cursor keys, the mouse will move slowly, but willgradually build-up speed - thus making longer distance movements easier.

Note that you cannot press more than one R/C button at the same time, sodiagonal movements are not possible.

Precision and ease of use will be more limited than a proper mouse, but thisoption does provide the user with added flexibility when giving presentations.

21

RS232 Computer Control

SetupAll of the functions of the CORIOscan Pro can be controlled from the Computer, usingthe RS232 port on the unit.

Using an appropriate lead and software, it is easy to communicate with the CORIOscanPro, but before the communications can be established first set the computer's serial portto:

8 bit data, no parity, 1 stop bit

Either no flow control, or hardware (RTS/CTS) flow control

Set the Baud rate on the computer and the CORIOscan Pro to the same value(usually 9600).

Sending commandsCommands are sent over the RS232 in one of two ways:

Send the 'adjust name' followed by = and a number (plus a carriage return) to alterany setting you see displayed on the lower line of the LCD display. E.g. If youwere using a terminal emulator program, you could type the following commandto immediately set flicker reduction to 6 lines:-

Flicker Red = 6

Send just the 'adjust name' (plus a carriage return) for to retrieve back the currentvalue for a setting. E.g. Typing the following returns the correct value back fromthe CORIOscan Pro unit (e.g. '6'):-

Flicker Red

Responses to commandsThe response from the CORIOscan Pro can be one of three things:

? if something is not understood, e.g. an adjust name is mis-spelt;

> if the command has been executed;

nnnnn (i.e. a five digit number from 0 to 99999, followed by a CR and LF) if asetting value is returned.

Notes on sending commandsSettings that are one of two values (e.g. NTSC or PAL), have to be sent as 0 or 1.

You only have to send a maximum of 4 characters in order for the commandname to be recognised - e.g. "Flicker Red = 6" could be shortened to "Flic = 6".

22

Spaces and line-feeds (ASCII code 10) are completely ignored.

You must always send a carriage-return (ASCII code 13) at the end of yourcommand or value request.

The CORIOscan Pro's response should at most be within 20ms of the receipt ofthe carriage-return character. But of course delays due to slow baud rates willplay a greater part than this.

The CORIOscan Pro's input buffer is limited to 32 bytes, so do not send any morecharacters (including CR, LF, etc.) than this.

For more information on controlling the different functions see the relevantsections earlier in this manual.

Restricting RS232 commands to certain unitsIf you have a number of units all connected to the same PC's serial port (i.e. running inparallel), then you can use the RS232 ID feature to restrict certain commands to go toonly certain CORIOscan Pro units. The following points outline this method:

Make each 'RS232 ID' setting unique to each CORIOscan Pro, unless you wanttwo or more units to respond to the same commands, in which case make themthe same ID value. The default value is 0.

Send the command 'ID Restrict nnn' where nnn is the number of the CORIOscanPro unit you wish to control (from 0 to 255).

Follow this with whatever commands you wish to send. Units where 'RS232 ID'is not identical to the 'ID Restrict' value will not respond to or acknowledge thesecommands.

To disable this feature, you have to make the RS232 ID the same on all units(recommended value 0), and of course set 'ID Restrict' to this value.

Changing Baud RatesDetails on how to change the Baud rate are in the Advanced Features section of thismanual, but the relationship between number and baud rate is given in the table below.

Any odd number up to 191 can be selected, but only certain Baud rates are generallyused. The most common ones are outlined in the table below. For numbers not includedin the table, the baud rate associated with those numbers can be found by using thefollowing equation:

Baud = 230400Number + 1

so if the number displayed on the CORIOscan Pro is 23 then

23

Baud = 23040023 + 1

= 9600

No. Baud Rate No. Baud Rate

1 115200 15 14400

3 57600 23* 9600*

5 38400 47 4800

7 28800 95 2400

11 19200 191 1200

*23, Baud rate = 9600 is the default setting.

24

Warranty & Returns Procedure

WarrantyYour unit comes with a two year warranty (valid from date of purchase), which coversfaults in the CORIOscan Pro hardware that arise from defects due to material orconstruction, when under normal use. The CORIOscan Pro will be repaired or replaced,as Vine Micros sees fit, free of charge within this period.

This warranty does not cover damage due to negligence, mishandling, accident, impropermaintenance, modification, or repair of the unit by anyone other than Vine Micros ortheir authorised representative.

Note that under all circumstances the warranty only covers losses up to the value of thereplacement cost of the CORIOscan Pro unit described in this manual (see 'Disclaimer'earlier in this manual).

Are you sure there's a fault?Please consult the appendix on trouble-shooting before sending a unit back. Most 'faults'are due to incorrect usage. If your CORIOscan Pro is not behaving as you think itshould, it may be worth trying an Engineering Reset (hold down MENU and - togetherfor a couple of seconds) - this will restore the unit to factory conditions.

To return a unit for repairFirst contact your supplier, who will obtain an authorisation number from Vine Micros.Please enclose with the unit details of why it has been returned, and failure details ifappropriate. Proof of purchase should also be included.

Units should be returned via insured courier or registered post (thus allowing a trace tobe made if goods are lost in transit), clearly stating the returns number allocated as thiswill speed up processing. Goods on their way to Vine Micros are the responsibility of thesender, and Vine Micros cannot be responsible for transit losses.

Appendix A - Getting the Best PossiblePicture

The CORIOscan Pro is a sophisticated scan-convertor, developed from Vine's 10 years ofexperience in computer to video conversion. As with all high-technology equipment,knowing how a device works will often let the user get more out of it.

Tips1. Use S-Video in preference to Composite Video, if your equipment has such an

input. S-Video keeps the colour and brightness signals in a video separate,whereas composite video requires extra filters to separate them electronically -these filters degrade the image.

2. Don't forget the ZOOM. If you have problems reading the small text, thenselecting the ZOOM mode will make things much easier, especially if using theComposite Video output. This is particularly useful for presentations.

3. If recording to video, try using H.Soften. This reduces the bandwidth of thesignal being sent to the CORIOscan Pro, and thus reduces artefacts and ghostingcaused by the video's filtering circuits.

4. Zoom modes may require a different Flicker Reduction setting. H.Soften isautomatically disabled in Zoom mode, but lowering the Flicker Reduction valuemay help to increase legibility of small text.

5. If you don't wish to record the display, use an RGB cable to link directly to theTV. RGB cables, such as SCART in Europe, will send the signal directly to theTV's CRT RGB circuits - bypassing any colour-decoding circuitry that tends to'smudge' Composite Video or S-Video signals.

6. The lower the graphics resolution and refresh rate, the better the 'horizontal'image quality. All scan converters store the computer image to be converted tovideo in their own internal memory, and to do so the graphics card's signal hasto be 'sampled' many times during each scan-line. Each sample stores one pixelof information in the memory. The number of samples taken is proportional tothe image quality - i.e. the more samples the better. Higher graphic resolutionstake less time to display each scan-line than lower ones, it means that there willbe more samples per line for lower resolution modes - and hence will give abetter 'horizontal' image quality.

7. The lower the graphics resolution, the better the 'vertical' image quality. TVshave a fixed number of lines available for displaying pictures - for PAL it is576, for NTSC it is 480, although some of these are off the top and bottom edgesof the screen. So the more scan-lines a graphics resolution has (e.g.. an 800x600

26

resolution has 600 scan-lines), the more difficult it is for the CORIOscan Pro tosqueeze all these lines into the limited number available on the TV.

8. If you experience line dropping, use a higher Flicker Reduction setting. Forlower resolutions like 640x480, you may even need to reduce the FlickerReduction setting.

27

Appendix B - Trouble ShootingIf problems are experienced, please go through these help topics in order to resolve theproblem. Otherwise, if you need to contact Technical Support, please have the followinghandy:

1. Details of the problem.

2. Whether the problem happens only at specific times, or has only just startedoccurring.

3. Hardware and Software revisions - which appear on the lower line of the LCDdisplay when you turn the unit on.

4. If the problem is image related, please try to find out the screen resolution andrefresh rate being used.

The picture on the video display is black and white.If you are using the S-Video or YUV outputs then ensure that all the cables are correctlyconnected. If you are using a PAL TV to display the output then the CORIOscan Promay be switched to NTSC mode, or vice versa. The LCD will display the currentstandard every few seconds in Status mode. See the Advanced Features section to changethis.

The picture on the video display is green or blank.The CORIOscan Pro is probably in YUV mode. In YUV mode, all other outputs aredisabled. Even if only the Composite Video or S-Video outputs are being used, thenRGB mode should be enabled. The LCD will display the status of the output mode everyfew seconds, the message should read 'Output Sig RGB', if it is set to YUV then see theAdvanced Features section.

There is no picture on the video display.If the LED on the CORIOscan Pro is off and there is nothing displayed on the LCD thenensure that the mains adaptor is connected properly and the mains switch is on at themains socket and the on/off power switch on the CORIOscan Pro is in the on (down)position.

If the LED on the CORIOscan Pro is on and the LCD is displaying the correct text thencheck that the monitor output from the computer is connected at both the computer andthe CORIOscan Pro VGA IN socket. Check that the output you are using from theCORIOscan Pro is also connected at the unit and the TV. Check that the target videoequipment is set to the correct line input (AUX or A/V selected).

28

There is no picture on the computer monitor.Check that the monitor output from the computer is connected at both the computer andthe CORIOscan Pro VGA IN socket. Check that the VGA OUT socket on the back of theCORIOscan Pro is connected at the unit and the computer monitor.

The unit does not respond to the RC02 remote control.Ensure that there are batteries in the RC02, that they are correctly inserted and that theyhave enough charge left. Check that the CORIOscan Pro is set to accept the RC02 (seeAdvanced Features section).

There is excessive flicker on the TV.Try using a different flicker mode. Turning the contrast down and the brightness up onthe TV can have a large effect on flicker.

The TV image is distorted.This often occurs where some of the areas of the image are very dark and others are verybright - and your TV isn't used to this! The solution is to adjust the contrast andbrightness settings on your TV to rectify the problem. If it's particularly bad, the ScreenSize settings may have been mis-set - do an Engineering Reset to over-ride these withfactory settings.

I cannot adjust the screen size by the amount I need.First, remember that the size settings cannot be altered in FREEZE mode. The unit isdesigned to allow size control of the computer display to fit your TV. Whilst in mostcases you will be able to make the display smaller on your TV than on your monitor, donot try to make it too large, or the image will be unstable. Also remember that youshould always have performed an AutoSet for your current resolution, so that theCORIOscan Pro has 'learnt' it.

Some colours come out incorrectly on the TV.First try altering the colour, contrast and brightness settings on your TV. These areusually set up for a very different reason than viewing computer graphics and may needchanging to suit. If you cannot achieve exactly what you desire then as a last resort alterthe ADC reference level (see Engineering section) until the correct colours are restored.(The CORIOscan Pro is set for a 0.7v p-p input voltage, but some graphics cards may bedifferent to this. Make sure you output something like a colour bar when adjusting theADC level.)

How can I reduce smearing?Smearing usually occurs on Composite Video connections, and is generally unavoidable -unless you can switch to using S-Video or RGB connections. It occurs because thebrightness and colour information is transmitted as one signal, and the two parts have tobe 'bandwidth-limited' to avoid them interfering with each other - see Vine's Free DTVGuide. If the smearing is offset, try altering the Y/C delay feature from theEngineering... menu.

29

The recorded image is poor.Standard VHS videos are not very good at recording the fine detail present in computergraphics. S-VHS decks offer much better quality, whilst professional decks will be evenbetter. Colour smearing is usually the first thing that causes a problem, but this isbecause your video isn't capable of recording the picture in its full resolution - it is not afault with the CORIOscan Pro or your video.

The LCD is either too dark or too light.The LCD contrast is not set correctly, by changing the angle that you look at the LCDyou should be able to read the text. See the Advanced Features section on how to alter thecontrast.

The mouse emulation isn't working.Check that the cable from the RS232 port on the back of the CORIOscan Pro isconnected correctly to the serial port that the computer uses for the mouse. Check thatthe infra red remote control is enabled on the CORIOscan Pro and that the remotecontrol has good batteries installed. Check that the CORIOscan Pro is set to 'RS232Mouse' mode. Mouse emulation is for Microsoft mouse compatible drivers only.

If problems arise, it is suggested that the computer be started up with a normal mouseconnected, and then the serial cables can be swapped over once the normal mouse hasbeen confirmed as working.

The serial communication from the computer isn't working.The computer needs to be set to the correct Baud rate, parity (none), stop bits (1) andflow control (hardware or none). The CORIOscan Pro is a standard DTE piece ofequipment, and its connections are much the same as an IBM PC's.
